Introduction

The given equation involves logarithmic functions and requires careful manipulation to solve for the variable x. In this article, we will explore the steps to simplify the equation and find the true solution.

Understanding the Equation

The equation given is $2 \log _3(6x) - \log _3(4x) = 2 \log _3(x+2)$. This equation involves logarithms with base 3 and requires us to apply the properties of logarithms to simplify it.

Applying Logarithmic Properties

To simplify the equation, we can use the property of logarithms that states $\log_a(b) - \log_a(c) = \log_a(\frac{b}{c})$. Applying this property to the given equation, we get:

$$2 \log _3(6x) - \log _3(4x) = \log _3(\frac{2 \cdot 6x}{4x})$$

Simplifying the expression inside the logarithm, we get:

$$\log _3(\frac{12x}{4x}) = \log _3(3)$$

Simplifying the Equation

Now that we have simplified the left-hand side of the equation, we can equate it to the right-hand side:

$$\log _3(3) = 2 \log _3(x+2)$$

Using the property of logarithms that states $\log_a(a) = 1$, we can rewrite the equation as:

$$1 = 2 \log _3(x+2)$$

Solving for x

To solve for x, we can use the property of logarithms that states $\log_a(b) = c \implies b = a^c$. Applying this property to the equation, we get:

$$x+2 = 3^2$$

Simplifying the expression, we get:

$$x+2 = 9$$

Finding the Solution

Now that we have solved for x, we can find the solution by subtracting 2 from both sides of the equation:

$$x = 9 - 2$$

Simplifying the expression, we get:

$$x = 7$$

However, we need to check if this solution satisfies the original equation. Substituting x = 7 into the original equation, we get:

$$2 \log _3(6 \cdot 7) - \log _3(4 \cdot 7) = 2 \log _3(7+2)$$

Simplifying the expressions, we get:

$$2 \log _3(42) - \log _3(28) = 2 \log _3(9)$$

Using the property of logarithms that states $\log_a(a) = 1$, we can rewrite the equation as:

$$\log _3(\frac{42}{28}) = \log _3(9)$$

Simplifying the expression, we get:

$$\log _3(1.5) = \log _3(9)$$

This equation is not true, which means that x = 7 is not a solution to the original equation.
